I've been waiting for a withdrawal from Frebitcoin for 5 days now... I wrote to support, and I got a reply that they received my request and that's it. That was 2-3 days ago... Except for writing to support we can open a scam accusation here on the forum, and we can do the same in some casino review sites (AskGamblers, TrustPilot...).
It is not surprising considering that they have been in problems for months, which means that their almost ten-year reputation has completely collapsed and that so far all such and similar problems are not the exception but the rule. I hope that in the end you will still get what is yours, even if you had to wait a lot longer than usual.
As for excuses, I would say that in any online business you can have as many excuses as you want, especially if you are relatively anonymous and the fact is that 99% of clients will not sue you even if they are 100% sure that they are right. Being honest and pretending to be honest are two different things.
